    • A method and system for efficiently transmitting data, to which scalable image coding has been applied over a single frequency network is provided. The system includes a control server which re-packetizes data packets, received from a multimedia server, into a scalable bit stream by separately encoding the data packets into a base layer and one or more enhancement layers, and at least one base station which adaptively multicasts and broadcasts the scalable bit stream, received from the control server, to a plurality of terminals located in the area of a cell. The at least one base station multicasts and broadcasts the base layer across the area of the cell, and adaptively transmits the one or more enhancement layers depending on channel status or terminal performance of the plurality of terminals.
    • 提供了一种用于有效地发送已经通过单个频率网络应用可伸缩图像编码的数据的方法和系统。 该系统包括控制服务器,其通过将数据分组分别编码为基本层和一个或多个增强层,将从多媒体服务器接收的数据分组重新分组成可缩放比特流,以及至少一个基站,其自适应地多播 并且将从控制服务器接收到的可缩放比特流广播到位于小区区域中的多个终端。 所述至少一个基站在所述小区的所述区域上多播和广播所述基本层,并且根据所述多个终端的信道状态或终端性能自适应地发送所述一个或多个增强层。

    • A method for creating a combined character in a Chinese character learning game includes a first step of creating a portion representing a pronunciation of a combined character as a graphic character; a second step of a portion representing a meaning of the combined character as an additional graphic character(s); and a third step of disposing the graphic character(s) representing the meaning and the graphic character representing the pronunciation according to the positional relationship of the combined character. In the method, a graphic character of the combined character is formed by combining the two or more graphic characters.
    • 一种用于在汉字学习游戏中创建组合字符的方法包括:创建表示组合字符的发音的部分作为图形字符的第一步骤; 将组合字符的含义表示为附加图形字符的部分的第二步骤; 以及第三步骤,根据组合字符的位置关系来设置表示意义的图形字符和表示发音的图形字符。 在该方法中,通过组合两个或多个图形字符来形成组合字符的图形字符。
